There are more than 60 companies that manufacture dental implants or the materials to make the restorations. Dentists now have many options to choose the best treatment for each patient. Be aware, however, that if an implant procedure is performed by one dentist and then a second dentist is needed for repair, your new dentist might not be familiar with the materials or have limited access to them.
Types of Dental Implants
The type of dental implant procedure used to place them is usually a factor in determining the category.
- Two-Stage Implants:- This two-stage procedure involves the placement of the implant in the jaw bone and the closing (stitching) of the gum tissue. After healing takes several months, minor surgery is required to attach an abutment or temporary restoration.
- Endosteal (Endosseous Implants):- These implants are placed in the jaw bone and are the most common type of two-stage procedure. Endosteal implants are used as an alternative to removable dentures or bridges. They can be either a screw type (threaded), cylindrical types (smooth), or bladed type.
- Single-Stage Dental Implants:- This single-stage procedure involves placing a longer dental implant in the jaw. The implant is placed on the jaw bone with the top level touching the gum tissue. After that, the gum tissue is closed and stitched, leaving the cap visible. After several months of healing, the temporary restoration and abutment can be attached to the head without the need for any minor surgery.
- Subperiosteal Implants:- These are placed on the jaw bone in the gum tissue with the metal post exposed to hold the restoration. They are very rarely, if ever, used today. Patients with low bone height used subperiosteals to keep dentures in place.
Dental Implants Coatings
While most dental implants are made from titanium, there is a possibility that the surface of the treatment can differ. This affects long-term integration and stability. Porous surfaces are more likely to contact bone than those made from machined titanium. You can also have a grit-blasted, acid-etched, and roughened surface. A plasma-sprayed hydroxyapatite coating and Zirconia (nonmetal) are other options.
Dental Implants Connectors
Implants can also be classified based on their head shape. All implants need to have a restoration or abutment attached to their heads. There are three types of connectors that can be used for this purpose:
- Internal Hex Connectors:- Shaped like a hexagon. An internal hex connector is a hole in the implant head where the restoration/abutment can be screwed.
- External Hex Connectors:- Also shaped like hexagons, these connectors can be found atop an implant head.
- Internal Octagon Connectors:- Shaped like an Octagon, the internal octagon connector has an opening in its implant head where the restoration/abutment can be screwed.
Dental Implants Sizes
Another way to classify implants is by their size (also known as platform), which determines where they can be placed in your mouth. Every case is unique and may require a different size. A fixture’s platform dimension and length are important factors in fixture selection.
- Standard Platform:- Standard dental implant sizes range from 3.5mm to 4.2mm in diameter. These implants are typically placed towards the front of your mouth.
- Wide Platform:- These dental implants are placed in the back of your mouth and range in size between 4.5mm and 6mm.
- Narrow or Minimal Body:- These dental implants are for patients who have insufficient space between the roots of their teeth to allow for a larger implant. They can also be used if the patient does not have sufficient bone density. These are temporary supports for provisional prostheses that are not yet osseo integrated.
